KWFontPicker

FKWFontPicker is a font picker control using UIPickerView.

KWFontPicker *fontPicker = [[KWFontPicker alloc] init];
[fontPicker setChangeHandler:^{
    NSLog(@"fontName=%@ pointSize=%.1f", fontPicker.font.fontName, fontPicker.font.pointSize);
}];
[self.view addSubview:fontPicker];

The following KWTextEditor would help to use the picker in most cases.

 

KWTextEditor

KWTextEditor provides a toolbar which has [Keyboard], [Font] and [Close] buttons upon KWFontPicker or iOS's software keybaord.

BASIC USAGE

KWTextEditor* textEditor = [[KWTextEditor alloc] initWithTextView:textView];
[textEditor setScrollView:self.scrollView];
[textEditor showInView:self.view];

FONT LIST

Available font names are shown on the left side of KWFontPicker. All fonts in iOS are listed per default. You could specify names with NSArray:

textEditor.fontPicker.fontList = @[ @"AmericanTypewriter", @"Baskerville",
    @"Copperplate", @"Didot", @"EuphemiaUCAS", @"Futura-Medium", @"GillSans",
    @"Helvetica", @"Marion-Regular", @"Optima-Regular", @"Palatino-Roman",
    @"TimesNewRomanPSMT", @"Verdana"];

FONT SIZE

Available font sizes are shown on the center of KWFontPicker. You could specify sizes by range:

textEditor.fontPicker.minFontSize   = 10;
textEditor.fontPicker.maxFontSize   = 30;
textEditor.fontPicker.stepFontSize  =  4;

or by NSArray:

textEditor.fontPicker.sizeList = @[ @9.5, @13.5, @17.5, @21.5, @25.5 ];

FONT COLOR

Available font colors are shown on the right side of KWFontPicker. 125 colors, which means 5 levels each for RGB, are listed per default. You could specify sizes by range:

textEditor.fontPicker.colorVariants = KWFontPickerColorVariantsNone; // no colors. use grayscales
textEditor.fontPicker.colorVariants = KWFontPickerColorVariants222; // 8 colors
textEditor.fontPicker.colorVariants = KWFontPickerColorVariants333; // 27 colors
textEditor.fontPicker.colorVariants = KWFontPickerColorVariants444; // 64 colors
textEditor.fontPicker.colorVariants = KWFontPickerColorVariants555; // 125 colors = default
textEditor.fontPicker.colorVariants = KWFontPickerColorVariants666; // 216 colors = web safe color

textEditor.fontPicker.grayVariants = 2; // black and white
textEditor.fontPicker.grayVariants = 16; // 16 gradients of grayscale

or by NSArray:

textEditor.fontPicker.colorList = @[
    [UIColor blackColor], [UIColor grayColor],   [UIColor whiteColor],
    [UIColor redColor],   [UIColor yellowColor], [UIColor greenColor],
    [UIColor cyanColor],  [UIColor blueColor],   [UIColor purpleColor]];

CALLBACK HANDLERS

Following handler blocks are available.

[textEditor setTextDidChangeHandler:^{
    NSLog(@"TextDidChangeHandler: text=%@", textView.text);
}];
[textEditor setFontDidChangeHandler:^{
    NSLog(@"fontDidChangeHandler: fontName=%@ pointSize=%.1f", textView.font.fontName, textView.font.pointSize);
}];
[textEditor setEditorDidShowHandler:^{
    NSString *mode = @"";
    if (textEditor.editorMode == KWTextEditorModeKeyboard) mode = @"keyboard";
    if (textEditor.editorMode == KWTextEditorModeFontPicker) mode = @"font picker";
    NSLog(@"editorDidShowHandler: %@", mode);
}];
[textEditor setEditorDidHideHandler:^{
    NSLog(@"editorDidHideHandler");
}];
[textEditor setCloseButtonDidTapHandler:^{
    NSLog(@"closeButtonDidTapHandler");
